Lars Hofhansl commented on HBASE-4583:
--------------------------------------
Some amount of boilerplate is necessary, because of the locking requirements
(i.e. cannot have an upsert method in HRegion, since the setup and the first
part of upsert need to have the same locks held).
Could have a boilerplate method and pass in a command object, but that would
not necessarily make it more readable.

> Currently Increment and Append operations do not work with RWCC and hence a
> client could see the results of multiple such operation mixed in the same
> Get/Scan.
> The semantics might be a bit more interesting here as upsert adds and removes
> to and from the memstore.
